PROSPECTING OR WELL-DRILLING DEVICE.

Application inea August 1o, 1923. serial, Nb. 656,728.

i upper end through which the core extracted from the hole being bored will be forced into a receptacle oi bucket normally located in the auger chamber below the inlet and adapted to be withdrawn for the removal of said core.

Another object of the invention is to produce a device of this character consisting of a sectional recessed auger, a detachable sectional hollow shank the bore of which communicates with the recess or bore and a detachable combined cutter and worm or bit.

A further object of the invention is to construct a core receiving receptacle or bucket the body of which is formed of two sections hinged together so as to be readily opened for inspection of the core.

A still further object of the invention is to provide simple and effective fastening means for securing the different elements together.

With these ends in view, this invention' `consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, l will describe its construction in detail, referring by 'numerals to the accompanying drawings forming a part of this application,

ln carrying out my invention as here ein# bodied, 2 represents a barrel of tubular cross section having a relatively long and narrow aperture or slot?) adjacent its upper end and provided at its lower end with notches ,4, preferably two in number, and` arranged diametrically opposite each other. On'th'e upper portion of this barrel is mounted the upper section 5 of the auger comprising a hollow body 6 and a helix or thread 7. y Said upper section is so located on the barrel that its upper end which is provided with a iange 8 terminates short of the upper end of the barrel and therefore said upper end of the barrel projects beyond this main portion ofl the auger. A portion of the thread as wel] as ofthe body is cut out to provide an inlet 9 corresponding in shape' and size to the slot oraperture 3 with which it coincides so as to provide an inlet to the interior of the barrel.

The lower edge of the hollow body 6 of the main auger section is provided with a tooth or projectionlO for coaction with a complementary tooth or projection 11 on the secondary auger section 12 which like the main auger section comprises a hollow body 13 and a helix or thread 14 which ismount ed upon the lower end of the barrel and has ribs or keys 15 formed there-with for registration with the notches or keyways 4. Both of these sections are secured to the barrel by means of suitable fastening devices such as screws 16 or their equivalent threaded through the body portions and into the barrel.

The lower end of the secondary auger member 12 projects ybeyond the lower'` end of the barrel 2 and has a restricted polygonal opening 17 with which registers a similarly shaped neck 18 ofthe combined worm and cutter 19. This member comprises 'a hardened worm or bit 20 the threads of which are preferably tapered and the hardened cutting elements or knives 21 which are substantially radially arranged and provided with beveled or sharpened cutting edges 22 in order to cut, grind or crush the earth and stone through which it passes. ln ,order to prevent accidental displacement of the worm or bit it may be secured to the secondary auger section by suitable fastening means 23 such as a screw or its equivalent.

AS shown in Fig. 3, the flange 8 of the main auger section is recessed as at 2d, said recess preferably being formed by cutting a portion of the Hange throughout two different arcs thereby forming shoulders 25 against which rests a filler 26 mounted in the larger portion of the recess and held in place by suitable fastening devices 27 such as stud screws and said filler is of greater thickness throughout a portion thereof than the flange 8 so as to form a projection 28 extending above the flange 8. rlhe filler '26 being of a width equal to the depth of the larger portion of the recess 24. and fitting in said larger portion of the recess forms with the remaining portion of the flange in the region of the smaller part of the lrecess-an arcuate slot 29 for insertion 'iron 39 the other web of said angle of the inlet closure or door to be later described.

The projection 28 of the filler 26 adapted toy register with a recess or slot 30 formed in the flange 3l of the detachable sectional shank 32 consisting of one or more sections 33. One of the shank sections detachably connected to the auger element by bringing its flange into contact with the flange of the auger which will cause the shank section to telescope over the projecting upperend of the barrel 27 plainly shown in Fig. 2, after which said flanges may be fastened together by suitable curing means 35 such as stud bolts or their equivalent. As the recess 30 in the flange 3l is of greater depth than the width of the filler 26 and its projection 28 an arcuate slot 36 is formed which coincides with the similar slot 29. L

At the far side of the inlet opening formed 'by the slots 3 and Q, when considered in connection with the direction of rol tation of the auger, is located a spacer strip 3S the edge of which is slightly set ba from the adj acentedge of the hollow ai body in the region of the inlet and on outside of this spacer and superi osed on this spaceris one of the webs of the any' projecting outward radially with relati to the auger and forming a fin l0 which latter entends over the edge of the spacer 38 and aligns with the adjacent edge of the hollow body of the auger in the region of the inlet thereby forming a guideway Lil. The angle iron and its spacer are secured in place by suitable fastening devices 42 such as screws or their equivalent it being understood that said angle iron spacer ei;- tends the full length of the inlet.

The inlet closure or door i3 shown in detail in Figs. and 8 is arcuate in cross section and is slidably mounted in the guideway ll with its upper end projecting through the slots 29 and 36 so that said closure or door may be readily moved up and down as occasion requires and if found desirable means may be associated therewith to limit the upward or outward movement of said door, such a meansj for convenience or illustrationj being here shown a stop a4 located at the inner or lower end thereof for contact with the lower face of the filler 26 when the door is opened. At the upper j end of the closure or door is located an ear l5 which may be formed integral with the upper edge thereof or produced in any other convenient manner. To this ear is adapted to be connected a suitable actuating device or rod a6, Fig. 2, and this lifting device or rod should be and preferably is of sectional formation in order that it may be extended as the auger is sunk into the ground.

Within the auger element of the device is located a removable core receiving receptacle or bucket l? which is adapted to be inserted through the upper end of the sectional shank and lowered into the poition illustrated in Fig. 2, at which time the upper open end of said bucket is below the lower end of the inlet. Said bucket is preferably formed of two semi-cylindrical sections 48 and 49 hinged along two longitudinal meeting edges as at 50. To the upper end of the bucket are hinged the bail rods 51, one to each bucket section, and are also loosely connected with a lifting rod 52 or its equivalent, said lifting rod also being of sectional formation whereby the upper end will project beyond the upper end of the uppermost shank section when the bucket is in place thereby permitting ready access to the lifting rod for the removal of the bucket.

.ln actual practice a suitable supporting frame may be provided and said frame may be of any desirable or preferred construction but must be of sufficient heightto permit the ready insertion of new sections of the shank as they are needed due to the entrance of the auger element into thel ground. The device may be revolved in any suitable manner as by man power or horse power after the manner of a windlass or it may be revolved by a suitable motor such as an electric, gas or steam engine and when operated by a motor the same maybe connected by suitable power transmitting mechanism with one of the shank sections.

In starting the operations of the device the auger element is connected to a shank section 33 and operated through said shank section until the auger element has been screwed into the ground a sufficient distance to permit the insertion of anotherk shank element. After this has been done the operations may be continued until the shank section connected directly to the auger element has almost completely entered the hole being produced at which time another section may be added and the op-v after and any hard soil or stones and rock encountered will be loosened up, broken or crushed by the cutters 2l and then elevated by the helix or thread of the auger until the soil cutaway reaches the region of the inlet where it will leave the helix and be forced by the iin Ll() into said inlet thence dropping into the core receptacle or bucket 47. As soon as the bucket is filled, which is determined by the distance the drilling device is sunk into the ground, the inlet closure or door i3 is closed by forcing down on the closure actuating rod 46. l/Vhen the inlet is closed the core receiving receptacle or bucket 47 may be withdrawn through the medium of the lift rod 52 and the soil which makes up the core of the hole can then be dumped out and examined or the bucket may be opened and the core examined while remaining in one section ot the bucket, An examination of the latter kind will disclose the contents of the core in the exact relation that it held before removal thereby indicating the condition of the different earth strata.

As soon as the soil in the bucket is removed said bucket is again inserted in the upper open end of the shank and permitted to drop into the chamber within the auger element and after the bucket is in place the inlet closure or door is again opened for the next step in the boring operation.

Tfrom the foregoing description it will be seen that l have provided a simple, strong and durable device which will be effective in its operations and enab-le an operator to examine the core of the hole to ascertain the condition and contents of the soil through which the device is passing.

Of course l do not wish to be limited to the exact details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
